HD143X

This is a Optoma HD143X.

Save up a little more and get the Optoma HD143X or look for other models in that seriesHD142X or HD141X. **Do not purchase a Projector that has pre-existing issues.**

Tbh I would’ve offered 200 and left it at that. You put an offer too low. The HD143X has a lamp lifespan of up to 12,000 hours in dynamic mode so it has a lot of lifespan in the other light modes. https://preview.redd.it/3b7eidlye2ng1.jpeg?width=1320&format=pjpg&auto=webp&s=6ee9b330957155469b323031b2647be188d5cfdb Don’t cook yourself on a good projector.

Hi op, this looks great! You should share this photo on the subreddit so others can see it as well. Don’t forget to tag me :) For the rainbow effect you could these settings: • Lower the BrilliantColor value. Try setting it to 1 or 2, or even turning it off if possible. A lower value results in more "pure" colors and often reduces the flickering sensation of the RBE. (Found in Image > Advanced) —— The speed of the color wheel and the brightness of the flashes impact how your eyes perceive the rainbows. • **Action:** Go to Options > Lamp Settings > Lamp Mode. • **Recommendation:** Switch to Eco mode. Reducing the overall light output makes the sequential color flashes less harsh against dark backgrounds, which is where rainbows are usually most visible. —— **Select the Right Display Mode** Some modes are "hotter" and use more aggressive processing which can trigger RFE. • **Action:** Go to Image > Display Mode. • **Recommendation:** Use Cinema or Reference. These modes prioritize color accuracy and usually result in a more stable image compared to "Vivid" or "Bright" modes. —— Rainbows are most visible in high-contrast scenes (e.g., a white candle in a dark room). • **Action:** In the Image menu, ensure your Brightness and Contrast are not cranked to extremes. • **Advanced Tip:** If you are in a dark room, lowering the contrast slightly can soften the "edge" where rainbows typically appear. —— Outside of the software settings, there are two physical things you can do: • **Ambient Light:** Adding a very dim "bias light" (like a low-power LED strip behind the screen or a small lamp in the back of the room) reduces the strain on your eyes and makes the RFE less jarring. • **Eye Movement:** Try to avoid darting your eyes quickly across the screen. RBE is most commonly triggered by rapid eye movement. Let me know if this helps!

You cant know something you never had basically. But that projector, once it starts to get burn in, thats it... Ewaste. A proper projector (can find on ebay even as low as 300e) will have a bulb which is replaceable and last about 10k hours (depends on system) and the bulbs at least for me cost only 80euro. Colorwheels cost 5euro a pop. All very easy diy change out. My projector is now iirc 15years old. 1080p60hz, optoma, long throw, its on very often just like tv, i changed maybe 3 bulbs so far... Has gaming settings reduce latency etc. great colors and contrast. Never used a screen even for it. Any plain color wall worked better than any of the budget screens. Have repainted wall matt white now and it works very well instead of those budget screens. 

With Blackfriday looming im trying to make a similar decision. Again like you i have a dedicated theatre room with full control over light. I currently have an old 1080p Optama projector with a fixed 100" screen. I need to look at replace the projector but with mini-led 100" tvs dropping drastically im not sure which route to take. main use is movies as I have a sepwrat3 family room with an LG c3 65".
